Dominated by mobile video traffic, the exponential growth of wireless data is placing severe demand on the radio frequence (RF) spectrum. The role of spectrum as a critical economic growth engine was recently highlighted in the President's Council of Advisors on Science and Technology (PCAST) report, which recommended creating 'the first shared-use spectrum superhighways.' The FCC has set in motion several initiatives that aim at identifying underutilized portions of the licensed spectrum and exploring new models for spectrum sharing among different types of users. In this project, the PIs propose to address the feasibility of dynamic spectrum access (DSA) operation over a large swath of the spectrum, encompassing the UHF portion of the TV White Spaces (470-698 MHz segment), the 3.5 GHz radar band, as well as other bands in the 1 to 4.4 GHz range that may later become candidates for DSA operation. If successful, this project is expected to have a transformational impact on many wireless communication systems, including extended-range wireless LANs, regional wireless area networks, wireless sensor systems, and coexisting cellular/WLAN systems (e.g., LTE-U and WiFi).The research agenda includes novel designs for a small form-factor reconfigurable antenna element that can operate over this frequency range, advanced antenna-circuit configurations for tunable narrowband carrier aggregation in the UHF TVWS segment, antenna configurations for supporting polarization diversity in MIMO-based DSA, optimized price-based cognitive MIMO (CMIMO) precoders that are founded in game theoretic techniques, and scheduling mechanisms for network-wide CMIMO operation. Optimizations at both the signal level (via MIMO precoding matrices) as well as the antenna level (via highly tunable small form-factor reconfigurable antennas) will be performed. The project also includes a comprehensive educational plan to further broaden its impact, including integrating research with undergraduate and graduate education, recruiting and outreach to minority and under-represented students, Research Experiences for Undergraduates (REUs), disseminating research data and findings through open access, and outreach to society through open-lab days and other activities.

以移动的视频业务为主的无线数据的指数增长对射频（RF）频谱提出了严峻的要求。最近，总统科技顾问理事会（PCAST）的报告强调了频谱作为关键经济增长引擎的作用，该报告建议创建“第一个共享使用的频谱高速公路”。FCC已经启动了几项举措，旨在确定授权频谱中未充分利用的部分，并探索不同类型用户之间频谱共享的新模式。在该项目中，PI建议解决在大范围频谱上进行动态频谱接入（DSA）操作的可行性，包括TV白色空间（470-698 MHz段）的UHF部分、3.5 GHz雷达频段以及1至4.4 GHz范围内的其他频段，这些频段以后可能成为DSA操作的候选频段。如果成功，该项目预计将对许多无线通信系统产生变革性影响，包括扩展范围的无线局域网、区域无线区域网、无线传感器系统和共存的蜂窝/WLAN系统（例如，研究议程包括用于可以在该频率范围上操作的小形状因子可重新配置天线元件的新颖设计、用于UHF TVWS段中的可调谐窄带载波聚合的高级天线电路配置、用于支持基于MIMO的DSA中的极化分集的天线配置、在博弈论技术中建立的优化的基于价格的认知MIMO（CMIMO）预编码器，以及用于网络范围CMIMO操作的调度机制。将执行信号级（经由MIMO预编码矩阵）以及天线级（经由高度可调谐的小形状因子可重构天线）的优化。该项目还包括一项全面的教育计划，以进一步扩大其影响，包括将研究与本科和研究生教育相结合，招募和推广少数民族和代表性不足的学生，本科生研究经验（雷乌斯），通过开放获取传播研究数据和发现，并通过开放实验室日和其他活动向社会推广。
